Nearly three years after Subaru announced that a true STI version of the WRX would never happen, the automaker has surprised fans with a change of heart. At the Tokyo Auto Salon 2025, Subaru revealed the WRX STI S210, a full-fledged Subaru Tecnica International creation that embodies the pinnacle of the STI philosophy. This highly anticipated model builds on the JDM-spec WRX S4 STI Sport R EX and reaffirms Subaru’s commitment to delivering high-performance vehicles that excite enthusiasts.
The S210 is powered by a 2.4-liter turbocharged boxer engine that has been re-engineered to produce 296hp and 375Nm of torque. These figures represent a notable improvement over the standard WRX available in Japan, although the S210 falls short of the 341hp and 450Nm torque offered by the S209, which was the last STI model available in the U.S. Subaru’s engineers have incorporated an upgraded exhaust system, revised intake ducts, and a recalibrated ECU to achieve these performance gains.
The engine delivers full power at 5,700 rpm and peak torque at just 2,000 rpm, ensuring a thrilling driving experience. Unlike its predecessor, the S210 features Subaru’s Performance Transmission, a continuously variable transmission (CVT) that has been refined to handle the increased output.
In addition to its enhanced powertrain, the S210 has been equipped with features designed to improve handling and performance. It rides on lightweight 19-inch BBS forged wheels fitted with Michelin Pilot Sport 4S tyres for superior grip and agility. Brembo brakes provide reliable stopping power, while electronically controlled dampers and a dedicated transmission fluid cooler ensure consistent performance during demanding driving conditions.
The S210’s exterior exudes aggression and aerodynamic efficiency, thanks to its bespoke body kit that includes a carbon fibre rear spoiler and black accents. Inside, the cabin reflects its motorsport pedigree with eight-way Recaro carbon bucket seats, red seatbelts, and piano-black trims. To emphasise its exclusivity, each S210 comes with a serial number plaque, a subtle reminder that this is not an ordinary WRX but a genuine STI model.
Subaru has confirmed that production of the WRX STI S210 will be limited to just 500 units, with order books set to open this spring. While pricing details remain under wraps, the extensive list of upgrades and its rarity suggests a premium price tag. The S210’s release signals a bold comeback for Subaru’s STI division, cementing its status as a leader in performance engineering while reigniting enthusiasm for the WRX STI nameplate.
